Requirements

Basic Javascript knowledge
No Deep Learning experience needed. You will learn everything you need to know

Description

This course will teach how to build and train an Artificial Neural Network from scratch using only Javascript(No library). We will use only an IDEA and a browser.

It is structured to help you genuinely learn Deep Learning by starting from the basics until advanced concepts. We will learn and code every component of a Deep learning architecture from scratch, uncovering all the magic behind Artificial Neural Networks.

To prepare the students for real life, we will develop our ANN framework following the TensorFlow API, and we will compare our implementation with Tensorflow.js, this way you will know what is under the hood of the Deep learning libraries.

In this course, we will create a handwritten digit recognizer model using three different model approaches:

Fully Connected Neural Network - Vanilla Artificial Neural Network
Fully Connected Neural Network (also known as a DenseNet) Using TensorFlow.js
Convolutional Neural Network(also known as a ConvNet or CNN) Using TensorFlow.js

Deep learning is a field of study traditionally reserved for researchers or engineers with advanced degrees, and because of that, many developers feel very intimidated to learn this technology. However, when you start learning the mystery behind the “magic”, you will realize that there is no reason to be intimidated. And that’s why I decided to create this course.

By following this course until the end, you will get insights and feel empowered to dive deep into the Deep Learning field to improve the experience of your projects.

Who this course is for:

Web developers curious about deep learning and AI
